Be itknown that I, REN EDMoND LA AUssoIs, engineer, a citizen of the French epublic, residing at Paris, France, have vented certain new and useful Improveents in Carburters, of which the followin is a speciiication.

. his invention relates to carbureters, more particularly for-explosion engines, in which are used mixtures of combustible liquids such as heavy oils, schist oils, lighting petroleums and industrial alcohols.

The chief object of the invention is to render carbureters able to produce vaporizing of a constant and uniform quality, whatever be the quality of the substance to be vaporized, supplied to them and delivered per unit of time, and more particularly when the said carbureters are of the type used on explosion engines with variable speed, to enable such engines to work in better conditions than hitherto.

bureter, for atomi'zin as well as heating,

ing corresponds a modification of the heating, so that when atomizing takes place, the temperature to which the oil or the like is brought, remains constant under any circumstances. v

rlhe invention further consists in certain other arrangements which will be more explicitly referred to hereinafter, more particularly an arrangement according to which, when it is' desired to vaporize industrially a mixture of liquid, it is atomized in the ence of a heating body which in its turn is raised to such .a temperature that the said mixture is immediately broughtto its eutec-` tic point, that is to say (hitherto simply considered as a temperature at which? takes place a henomenon curious from the purely scientific point of view) at which any mixture of liquid lis vapor-ized without any dissociation taking place, and without any fractional .distilla--` tion taking place before the vaporization.

atomizing, a circular spray of particles traveling'outward, and also a device for sending the llquid into the said sprayer with suiiiclent pressure.

The heating means, above referred to, conslsts of a cylindrical part or annular ring b arranged concentrically with the sprayer a, as well as at the same level vand surrounded by an electric resistance c lconnected to a source of current suitable for feeding it, for example, storage batteries d which may be combined with the motor.

Both the sprayer and the heating means are arranged in an air tight chamber e so that the working takes place with the entire exclusion of air, in such conditions, that despite the presence of the heating means, the vaporized and atomized liquid cannot become ignited.

To the chamber is connected a nozzle f1 of an inlet f so that the vapors escaping from the said nozzle, can mix with air in the desired proportion, in order to form a suitable explosive mixture.

As soon as the atomized liquid comes into contact with the heating means, it is raised to its eutectic point, and as soon as the motor has been started, a more perfect working of the motor is obtained than when it is fed inthe usual manner.

The nozzle of the sprayer a may form a Venturi nozzle, which can be advantageously effected, in the case where it is desired to distribute the liquid in a circular spray, by using a tubular part a1 with a widened porcomprising a circular bevel 1, and also a rod as'which has a 'sliding it in the said tube, as indicated at 2. The tube is also provided with a helical groove 3 and terminates at its outer end in a thickened portion a? also having a circular bevel 4. The two bevels are arranged to oppose each other and are preferably held at the proper distance a art by the liquid to be atomized, provide it is under sufficient pressure, and ultimately form the discharging nozzle of the sprayer.

of the discharging nozzle of which varies in cross-section in accordance with pressure atI . under which the liquid is placed by the speed of the motor.

A tube i with a pressure gage is provided, acting partially as the air reservoir of a pump.

A by-pass g1 is provided on the pump g so that if the latter delivers too much, the liquid supplied can return .directlyto the tank from which it is taken.

A pipe j connects the bottom portion of the chamber e to theconstant level tank h so that if the output of the sprayer a, is ex cessive, the excess of liquid thus supphed,V

returns to the said tank which is preferably provided with acooling arrangement, for instance with ribs h1.

A rod k exposed to the action of a spring la acts on the widened portion a2 of the central rod of the sprayer aand controls the cross-sectional area of the nozzle in the reverse direction to the action exercised by the charge of liquid to be atomized.

The throttle f2 of the said inlet f is connected to the atomizing means so that the output of the said means is determined by the position given to' the said throttle (or conversely) this arrangement being obtained, by combining-with the controlling.

rod k, a finger lZV adapted to press on the -same and mounted on a shaft u carried in a suitable bracket v and to which shaft is. connected a connecting rod m, having suitable levers to the said throttle. A torsion spring n is provided for the shaft u, as shown `in Fig. 2.

The tube z' is rendered 'suitable for stor-v ing, at each closure ofthe said throttle, a reserve of fuel calculated to facilitate the next starting or acceleration.

The source of electricity for feeding the resistance c, may not only be storage batteries al, but also an electro-magnetic machine o suitable for recharging the said batteries and connected'to the motor so that its speed is a function of the speed of the engine. The said machine can also be utilized as an automatic starting device suitable for starting the said motor, and its dimensions should be such thatlwhatever be the speed of the said motor, and therefore of the pump g, the, resistance c always remains at the same temperature, in order to raise the atomized liquid impinging against it immediately to its eutectic point. The machine should alsobe proportioned so the said resistance acts as an automatic regulator of current for recharging the batteries. For this reason, the machine o has two excitation series o1 and o2--the iirst'in order to act as a self starter, and the second in order to act in its normal part. The free end of the said excitation series and the non-corresponding brush are connected respectively to the first and to thesecond of the termmals of the 'batteries d, a switch p1 one of the ends of the resistance c.

is not complied with.

being at the same time inserted into the circuit thus formed. From the same circuit is branched oif a pair of conductors which 'brush are connected respectivel to the first of the terminals of the batteries d and11 ltlo v e second of the latter ends is connected to a contact g, in front of which are mounted two other 'contacts a" and s which are connected respectively to the second of the terminals of the batteries d and to a conductor branched on the conductor connecting the said first terminal of the batteries d to the free end of the excitation series o2. In the length of the latter conductor is inserted a switch p2 which if desired could be connected to the said switch p1 so that one switch is opened when the other is closed and conversely. On the said contact g is mounted a kind of contact breaking switch t suitable for connecting it to the batterles d,

and connects on the contrary the contacts.

g and s when the condition just` formulated The invention 1s not limited to the construction more particularly specified, but

comprises on the contrary those modificatons,in which itis applied to the feeding of explosion motors of all kinds and also to burners for `steam generators; in which case ,they inventionl would be the same as that described, with the difference that an inlet pipe would no longer be used and a separate engine connected to the distributing pump g and having automatic regulation, by completing the installation by combining a thermostat or pressure regulator with the same.
